ABSTRACT

Embodiments of a method and apparatus of image search are provided. An exemplary method of image search includes: receiving a request and returning a web page, where the returned web page allows uploading an image and adding annotation content for the image; receiving and storing the image and the annotation content for the image; and providing the annotation content for the image as a search index to an image search engine. Using the disclosed method and server, more searches related to information in an image can be provided. Moreover, because more information related to merchandise in an image can be provided to a viewer, it is believed that more online transactions can be facilitated.

RELATED APPLICATIONS

This application claims priority to and is a continuation of U.S. patent application Ser. No. 12/663,743, filed Dec. 9, 2009, entitled “IMAGE SEARCH APPARATUS AND METHODS THEREOF” which is a national stage application of international patent application PCT/US09/64210, filed Nov. 12, 2009, entitled “IMAGE SEARCH APPARATUS AND METHODS THEREOF” claiming priority from Chinese patent application No. 200810173071.6, filed Nov. 26, 2008, entitled “METHOD AND SERVER TO PROVIDE FOR IMAGE SEARCH”, which applications are hereby incorporated in their entirety by reference.

TECHNICAL FIELD

The present disclosure is related to a field of computer network technology, and particularly to an apparatus that enables image search and methods thereof.

BACKGROUND

In addition to allowing users to conduct text-based searches, image-based searches are also presently available on the Web. Accordingly, a user may conduct an image search once the user is connected to a website.

Conventional Web search engines such as Google, Yahoo and MSN have already provided image searching services. This kind of searching implements an inquiry function by building up indices based primarily on filenames of images and is therefore similar to an ordinary textual keyword search or a keyword search based on a filename. Although this filename-based searching method may satisfy typical search demands, it nevertheless fails to provide further search related to information of the image.

DETAILED DESCRIPTION

Methods and apparatus of image search are described using the exemplary embodiments provided below.

In order to allow one ordinarily skilled in the art to understand the technical schemes of the present disclosure in a better way, the technical schemes in the exemplary embodiments of the present disclosure are described in a clear and complete manner below through the accompanying figures associated with the respective exemplary embodiments. It should be understood that the exemplary embodiments described herein only constitute parts of, not all, the embodiments of the present disclosure.

Generally, the Web includes user clients (e.g., user terminal devices), networks and servers (such as a Web server). A user client may be a Web user terminal such as a desktop, a laptop, a smart device having a Web browsing function (e.g., Personal Digital Assistant, PDA), a Mobile Internet Device (MID), or an Ultra-mobile Personal Computer (UMPC), etc. This user client may request another process (e.g., a process provided by a server) to provide a certain service in a Web environment (typically the Internet environment, for example).

A server is generally a remote computing apparatus which is accessed through a communication medium such as the Web (typically the Internet, for example). Moreover, the server can generally provide services to multiple user clients over the Web. The process of providing a service includes: receiving a request from a user client, collecting data related to the user client, and returning information, etc. Essentially, the server plays a role of an information provider in a computer network. A server is typically on the service providing side and its service content may be configured by a service provider. An example of this service provider is a website of a Web service company.

A method of image search in accordance with a first exemplary embodiment of the present disclosure is described as follows. FIG. 1 shows a flow chart of this exemplary embodiment. As shown in FIG. 1, the exemplary embodiment includes the following actions:

S101: A user client submits a request to a server through a network, requesting a web page to be opened.

Usually, a user client opens a web page by entering a Uniform Resource Locator (URL) into an address field of a browser or by being directed to a web page through a URL link. Basically, the user client submits a request to a server, such as a server of a certain website for example, to open a web page of the website.

S102: The server returns the requested web page to the user client.

In one embodiment, the server may allow the user client to upload an image onto the returned web page and add an annotation for the uploaded image.

Furthermore, in another embodiment, a function of adding a frame label for part of the image may further be provided in the web page returned by the server. An “annotating” technology exists in JavaScript implementation and is implemented through JavaScript objects and methods.

Specifically, certain technology using Asynchronous JavaScript and XML (AJAX) may be utilized to achieve this function. AJAX is a web page development technology for creating interactive web page applications. AJAX applications use Web browsers that support the above technology as operating platforms. Currently, these browsers include: Internet Explorer, Mozilla Firefox, Opera, Konqueror and Safari of Mac OS. Yahoo has disclosed a series of AJAX design patterns when releasing AJAX toolkits which are called the Yahoo! User Interface (YUI). These toolkits of Yahoo are AJAX toolkits released after Yahoo acquired a number of Web2.0 websites, and have more complete code annotations as well as rich and detailed documentation. As the number of YUI components continuously increases, YUI includes such components as AJAX, within which are toolkits obtained after packaging low-level JavaScript (which include connection, event, Dom, animation and dnd). Furthermore, a group of high-level JavaScript ActiveX controls, which currently comprise AutoComplete, Calendar, Container, Menu, Slider and TreeView, are included. The relatively pioneer website http://www.fotonotes.net, the famous Flickr website, and even the Chinaren website all provide similar frame labeling function for an image.

Accordingly, the user client may add a frame label to an image on a Java-supported browser using one or more of these technologies. Specifically, these technologies may be used to provide to a user client a frame labeling function for part of the image.

S103: The user client sends the image and annotation content added for the image to the server.

Besides uploading an image, the user client may add annotation content for the image through a text box provided in the web page.

As shown in FIG. 2, in one embodiment, a text input box and a submit button may be provided near the image in the web page to allow a user client to enter textual input in the text input box as annotation content for the image to annotate the image. Upon entering textual input as the annotation content of the image in the text box, the user client clicks the submit button to submit to the server the textual input, as the annotation content of the image, along with the image. Simply put, the added annotation content of the image is also sent to the server.

It should be noted that the annotation content may be a description written by the user client and may be related to a merchandise shown in an image in particular to describe, for example, texture, material, place of production, unit price, function and use of the merchandise, a URL address of an online store of the merchandise's seller, contact method of the seller, and/or comments for the merchandise.

At S103, besides adding the annotation content for the image, the user client may further add a frame label to the image using the provided frame labeling function, and send the frame label to the server. In one embodiment, the frame label can be sent along with the image and the annotation content to the server.

FIG. 3 shows an intuitive example of a frame label. Upon the user client clicking on a button labeled with “Add” or “Add Frame Label”, for example, at the bottom of the image in the web page, a default frame appears on the image. In one embodiment, the user client may move the frame to a desired position on the image and adjust the size or aspect ratio of the frame, etc. Furthermore, in another embodiment, an annotation may be provided beside the frame and a textual input may be added within an annotation box.

Therefore, if the user client wants to label the frame and add annotation content for the image in the web page, the annotation content may be added to the annotation box of the frame label.

In one embodiment, the frame labeling operation can be implemented by JavaScript in the user client while privilege management of the frame label may be realized by the server.

With respect to online transaction platforms (e.g., such as business-to-business, or B2B, business-to-consumer, or B2C, and consumer-to-consumer, or C2C, websites), the content of the frame is typically a product (in the image) that is framed by the user client. Within the annotation content of the frame label there may be a description of the product and/or a URL address of the seller's online store, for example, as described above.

It should be noted that, from the receiving perspective of the server, in various embodiments, S103 may include an activity of submitting an image and adding annotation content as well as a frame label for the image by a certain user, an activity of submitting different annotation contents for the same image by different users, or an activity of submitting different annotation contents for the same image by the same user in multiple times. In one embodiment, submitting different annotation contents for the same image by the same user in multiple times may include separately submitting multiple annotation contents and frame labels for the same image in multiple times.

In conventional web page technology, after a user client adds annotation content for an image in a web page or adds a frame label for the image (in addition to annotation content) in the browsed web page, an activity of submitting them to a server entails sending the image, the annotation content and the frame label (if included) to the server. It is noted that the image is included in the submission regardless of whether the image previously existed in the web page or has been uploaded from the client in the current browsing event. On the other hand, in case that the image pre-existed in the web page, an embodiment of the present disclosure provides an additional option of submitting only the annotation content for the image and the frame label (if included) to the server without resending the image. This avoids transmitting the same content (i.e., the image in the web page in this case) back and forth between the server and the user client, thereby saving bandwidth and resulting in fast interaction for improvement of user browsing experience.

S104: The server stores the image and the annotation content for the image received from the user client.

Some implementation methods for storing annotation content for an image by the server according to various embodiments are described below.

1. In one embodiment, the server stores the annotation content in a database and associates the annotation content with the image.

This method is simple and implementable, with relatively good scalability and maintainability. Currently, image websites such as Flickr and Yupoo adopt this scheme.

One skilled in the art can appreciate that the database described herein may be a separate device connected with the server or a component in the server such as a software-implemented database in the server. This type of method does not limit the size of the content that can be annotated by the user client, thus allowing storage of a large amount of information.

2. In another embodiment, the server stores the annotation content in auxiliary information of the image and then stores the image.

For example, when the image is in jpg or jpeg format, its file characteristics (i.e., pursuant to the Exif specification) include a reserved tag for user comments. In the jpg or jpeg format standard, this tag is reserved and not defined, and thus has no restriction and is available to be defined by a developer. The following table is a table showing a portion of the Exif specification regarding the jpg image format.

TABLE 1 Exif Image File Directory Characteristics Tag ID Tag Name Field Name Dec Hex Type Count A Tags Relating to Version Exif Version Exif Version 36864 9000 UNDEFINED 4 Supported Flashpix version FlashpixVersion 40960 A000 UNDEFINED 4 B Tag Relating to Image Data characteristics Color space information ColorSpace 40961 A001 SHORT 1 C Tags Relating to Image Configuration Meaning of each components ComponentsConfiguration 37121 9101 UNDEFINED 4 Image compression mode CompressedBitsPerPixel 37122 9102 RATIONAL 1 Valid image width PixelXDimension 40962 A002 SHORT OR LONG 1 Valid image height PixelXDimension 40963 A003 SHORT OR LONG 1 D Tags Relating to User Information Manufacturer notes MakerNotes 37500 927C UNDEFINED Any User Comments UserComment 37510 9286 UNDEFINED Any E Tags Relating to Related File Information Related Audio File RelatedSoundFile 40964 A004 ASCII 13 

As shown in the row of boldface letters in Table 1, the Exif characteristic of the jpg format has a reserved tag for user comments. This tag is of undefined type and has no restriction on length, thus allowing an addition of content by a user or a developer.

This tag allows the annotation content to be stored in the auxiliary information of the image.

Similarly, images in other formats such as images in bmp or png format can have annotation contents to be stored in respective auxiliary information of the images. In the interest of brevity, the details are not described herein.

In one embodiment, when the submitted content further includes a frame label for the image as described above, the server not only stores the image and the annotation content for the image that are received from the user client but also stores the frame label for the image. In particular, the server may further store the annotation content within the frame label through one of the above two methods.

In one embodiment, the above two methods may store a URL link and have the information stored in a tabular form. Generally, for shopping websites such as online transaction platforms (e.g., websites of the B2B type, B2C type or C2C type), an address where the product can be purchased (e.g., URL address of the seller) may be stored. Moreover, the information can be categorically stored in a tabular form. Furthermore, these two methods both support development by a user or a developer, thus providing more varieties of information storage.

In one embodiment, the server needs to create an annotation parser in the latter method. When an annotation is stored, the annotation parser writes the annotation content into the auxiliary information of the image. Accordingly, in one embodiment, when the image requested to be displayed is returned to a client (e.g., after performing the activity of S105 described below) and the search engine sends out a request for retrieving corresponding annotation content, the annotation parser parses out the annotation content from the auxiliary information of the image and returns the annotation content to the user client or returns the annotation content to the user client through the search engine.

S105: The server uses the annotation content of the image as a search index which is provided to an image search engine.

In one embodiment, the image search engine is implemented using a separate device of the website. Alternatively, the image search engine may be integrated in the server. Deployment of this kind depends on scale, implemented functions and needs of associated website. In other embodiments, other plausible means may also be used.

Most existing image searching techniques conduct an image search using an image name. As the filename of the respective image, the image name is similarly limited by word count and format, and so forth. For example, total word count, inclusive of extension and separator(s), generally cannot exceed two hundred and fifty-five bytes in Windows operating system. Besides, a filename cannot provide a URL link and cannot have formatted content. As a result, a large amount of information cannot be stored in a filename.

At S105, annotation contents for images are used as search indices. In one embodiment, the database performs a specific ordering of the indices, e.g., establishing reverse indices, to allow more search inquiries that are faster and more comprehensive. As such, a search result can have more abundant contents related thereto. Upon receiving a query and obtaining a result based on a keyword associated with the query as well as having the search engine searching through the indices, all annotation contents and associated images contained in the result are returned to the inquiring party. In some embodiments, in order to provide more images and information in the returned result, the images are provided in thumbnail size and a certain selected number of words of annotation contents are returned.

For the image returned after search, the user can see the information therein, particularly the URL address of the seller in the annotation content or the seller address where the product labeled by the frame label is sold. The user can click on the address to be directed to a web page of the seller of the product, thereby leading to a transaction conducted between the user and the seller. In one embodiment, the URL address needs not appear in a form of a complete linked address but rather may be an icon or a text containing the linked address (such as, for example, texts or icons of sellers that usually appear in TaoBao.com). Furthermore, icons for instant messaging with the seller (such as, for example, portraits of sellers that are usually appear in TaoBao.com) may further be included. Upon clicking on a portrait by the user, an instant messaging application is initiated to allow real-time communication with the seller. Alternatively, the instant messaging application may be opened in the web page to allow instant messaging with the seller.

In one embodiment, between S103 and S104, additional activities that may be included are described below.

S103′: The server examines the annotation content submitted by the user.

An examination includes one or a combination of two of the following meanings: examination of the legitimacy of annotation content and examination for the best annotation content.

Examining legitimacy of annotation content includes the following according to one embodiment. During the activities of adding annotation content or submitting multiple annotation contents for the same image by a user as described above, annotation content containing word(s) that is/are included in a predetermined illegitimate word lexicon is/are filtered out. This ensures annotation content to conform to the laws of the country and social conscience, etc.

With respect to examining for the best annotation content, the best annotation content may be selected by a human operator in one embodiment. For instance, the merchandise in an image may be described by multiple annotation contents. Different annotation contents may have different details and different accuracies. A staff may manually select the best annotation content while deleting the other annotation contents.

In one embodiment, the server may support activities of submitting multiple annotation contents for a given image. In another embodiment, the server may provide a format of question and answer and a scoring rule for annotation content submission in order to facilitate more and better annotation contents provided by user clients.

In one embodiment, the website may divide annotation contents submitted by users into two types: a question type and an answer type. When submitting annotation content, a user may select the type to which the annotation content belongs, i.e., a question type or an answer type. Take the question type as an example first. Upon seeing a product in an image, a user performs frame labeling of the product in the image and adds an annotation asking what brand and price of the product are. Moreover, the web page provided by the server may further have an option of product categories such that the user may select a category associated with the product when asking questions about the product. Other users may answer the questions in the image and select these answers as belonging to annotation content of an answer type when seeing the image and the annotation content. In one embodiment, during the process of answering the questions, the server may set up the option of product categories in the provided web page. The person who answers the questions can select a category associated with the product when answering the questions related to the product. Upon seeing the answers, the user who raises the questions can evaluate the answers (if there are multiple answers, for example) such that the user who provides a better answer will receives a higher score. More importantly, more and richer annotation contents for an image are encouraged through constructive mechanism such that better annotation content is made prominent. Moreover, this constructive mechanism facilitates acquisition of more objective and rational annotation content.

In one embodiment, when the server organizes a format of question and answer and a scoring rule for annotation content submission with users providing more annotation contents, the submitted annotation contents may be examined pursuant to the description of the activity of S103′.

A practical scenario is used to explain the details of the above description and provided herewith. On an online transaction platform, a buyer may not know a certain product in a certain image, e.g., a shirt worn by Jay Chou on the cover of CD <<I am very busy>>, and wants to obtain information of the product. The user may promulgate the image on the web page (i.e., the cover of the CD <<I am very busy>> by Jay Chou) and adds annotation content (e.g., the annotation content is of a question type, inquiring product information of the shirt in the image). The user may further frame and label the shirt in the image to intuitively point out his/her desire to know the information of the product. Moreover, while questioning, the user may select a category associated with the product in the web page, such as clothes/shirt, for example. Upon seeing the image, other users or the seller may continue to add annotation contents for the shirt in the image. For example, if the annotation content is of an answer type, the annotation content may include answers to the questions (e.g., information such as brand, texture, material and style of the shirt) and may further include an address of the seller of the product such as a URL address. The other users or the seller may also select a category associated with the product when adding the annotation contents or when answering the questions. Furthermore, any interested user may acquire this image through searching to obtain the questions and the answers associated with the image and enter into a transaction web page of the product through the seller's URL link in the annotation content to complete a trans action.

Tasks that can be processed by a server, in the context that the server can organize a format of question and answer and a scoring rule for annotation content submission, are described below.

When submitting annotation content, a questioner may select a category to which the annotation content belongs, i.e., a question type. Specifically, the questioner performs frame labeling to a product in an image on a web page and adds an annotation, asking about brand and sale price of the product. In one embodiment, the web page provided by the server may have an option of product categories. Hence, the questioner may select a category associated with the product when asking a question about the product. Upon seeing the image and the annotation content, other respondents (possibly including the seller of the product) answer the questions in the image and select corresponding answers as belonging to annotation content of an answer type. In one embodiment, the web page provided by the server may have an option of product categories when a respondent answers the questions. In this way, the respondent may select a category associated with the product. A submitted question may be answered by a number of respondents. As such, a number of answers may be received for the same question. After seeing the annotation contents answered by the respondents, the questioner provides scores to the answers. In the event that there are multiple answers, each answer has a corresponding score as produced according to the scoring rule provided by the server, with one of the answers having the highest score. The scores for these answers can be detected by the server. Therefore, the server may reckon the answer having the highest score to be the best answer which is then treated to be the answer for the submitted question and displayed in the annotation for the product in the image.

In one embodiment, the first method at S104 may be implemented in the following manner: the server stores in the database the best annotation content, which is the annotation content with the highest score, detected after scoring and associates the best annotation content with the image.

In another embodiment, the second method at S104 may be implemented as follows: the server stores in the auxiliary information of the image the best annotation content, which is the annotation content with the highest score, detected after scoring and stores the image.

Moreover, the annotation content (including the above best annotation content) detected by the server most likely includes a URL address such as an address of the seller of the product. The server may find a web page that is linked by the URL address in the annotation content. For example, the web page that is linked by the URL address is a web page describing the product. Regarding web pages having product descriptions, respective product descriptions on the web pages can be obtained by the server. For example, a product description in a seller store on TaoBao.com may be obtained by a server of TaoBao.com. In one embodiment, the first method at S104 may further include: (1) the server further stores in the database the product information in the web page that is linked by the URL in the annotation content and associates the product information with the image; or (2) the server further stores in the auxiliary information of the image the product information that is linked by the URL in the annotation content and stores the image.

In one embodiment, the product description in the web page has a specific format in most situations. For example, a web page of product description on TaoBao.com has “treasure details” in which a specific category item is described. For instance, the following various category items are described in treasure details of a clothes-related web page on TaoBao.com. An example description of various category items for a certain “shirt” is shown in the following table:

Design: Long sleeve Style: Korean Brand: other Price Range: 31-70 dollars Collar: Stand Collar Pattern: Pure Color Season(s): Spring, Summer and Fall Texture: Other Color: White Size: One-size-fits-all Clothes Length: medium-long (clothes length: 50-70 cm)

Another example description of various category items of a certain “cell phone” is shown in the following table:

Brand: iPhone Apple Model Number: iPhone 8G (3G Version) Cell Phone's Price Range: Cell Phone's Release Time: 2008 3001-5000 dollars Network Type: 3G External Appearance: Bar Screen Color: 1.6 million Treasure Quality: Brand New Ring: MP3 ring Camera Resolution: 0.2 M Is A Smartphone: Smartphone Operating System: iPhone

It should be noted that the above specific category items may be options selected by the seller based on options provided by the server when the seller fills in the product information. Therefore, the server can easily obtain the specific formatted descriptions related to product information on the web page through the address linked by the URL of the web page, and process these specific formatted descriptions according to the above method in (1) or (2). These information descriptions are very useful to other users in understanding the product in the image when the image is browsed and obtained after search.

It should be noted that realizations of the above transactions have important significances to online transactions of the B2B, B2C and C2C types. First, existing online transaction platforms merely provide text search for a product. In a situation when a user does not know information related to a product, it is difficult to use accurate wording to describe the product. As such, it is difficult for the user to find the desired product through a text search. In certain sense, this kind of mode fails to satisfy the needs of a user in understanding and purchasing a product. On the contrary, the exemplary methods of the present disclosure allow an online transaction platform to immediately provide product information through recognition of a product displayed in an image by a user, and direct the user to an address where the product is for sale to conduct further transactional activities. As a result, factors that hinder a transaction due to a lack of information are greatly reduced, thus enhancing intuitive user experience. Second, only a seller can display an image of its product as well as collect and provide product information previously. For a user who submits a purchase request, the product is hard to be recognized intuitively in the form of text, thus hindering a transaction from concluding. The exemplary methods of the present disclosure, however, allow a seller or other users to provide product information related to a product in an image, thus facilitating a transaction to be concluded between the seller and a buyer.

The first exemplary embodiment is described from the perspective of the server below. FIG. 4 shows a flow chart in accordance with one embodiment.

S401: The server receives a request and returns a web page. In one embodiment, a user client is permitted to upload an image and/or add annotation content for the image in the returned web page.

In the returned web page, at S401, adding a frame label for part of the image is further permitted in another embodiment. As such, a user client may add a frame label for an image on a browser using this technology. Specifically, through this technology, the user client is provided with a function of frame labeling for a certain part of the image.

S402: The server receives and stores the image and the annotation content for the image.

A text for annotation content may be a description written by the user client related to a merchandise in the image in particular, such as, for example, texture, material, place of production, unit price, function and use of the merchandise, a URL address of an online store of a seller of the merchandise, contact method of the seller and comments for the merchandise, or any combination thereof.

The content of the frame is typically a product (in the image) that is framed by the user client. Within the annotation content of the frame label may be a description of the product and/or a URL address of the online store of the seller, for example, as described above.

In one embodiment, if the user client performs frame labeling for the image in the web page and adds annotation content, the annotation content may be added within an annotation box of the frame label.

It should be noted that, in various embodiments, the server may receive a submitted image and annotation content as well as a frame label for the image added by a certain user, different annotation contents for the same image submitted by different users, or from the same user in multiple times, for example. In one embodiment, receiving annotation contents multiple times from the same user may further include separately receiving multiple annotation contents and frame labels for the same image multiple times.

Two implementation methods for storing annotation content for an image by the server are described below.

1. In one embodiment, the server stores the annotation content in a database and establishes an association between the annotation content and the image.

2. In another embodiment, the server stores the annotation content in auxiliary information of the image and then stores the image.

For example, when the image is in jpg or jpeg format, the server may store the annotation content as user comments in accordance with the Exif specification.

S403: The server reckons the annotation content for the image as a search index and provides the annotation content to an image search engine.

In one embodiment, between S402 and S403, additional activities that may be included are described below.

S402′: The server examines the annotation content submitted by the user.

In one embodiment, the server may organize a format of question and answer and a scoring rule for annotation content submission to facilitate more and better annotation contents provided by user clients.

In one embodiment, when the server organizes a format of question and answer and a scoring rule for annotation content submission, the following procedures may be used to implement storing the annotation content into a database and associating the annotation content with the image by the server:

storing in the database the best annotation content detected upon scoring and associating the best annotation content with the image by the server.

In one embodiment, the following procedures may be used to implement storing the annotation content in auxiliary information of the image and storing the image by the server:

storing in the auxiliary information of the image the best annotation content detected after scoring and storing the image by the server.

In one embodiment, when the annotation content includes a URL address of the seller of the merchandise, storing the annotation content in the database and associating the annotation content with the image by the server may include:

storing in the database the product information in the web page that is linked by the URL in the annotation content and associating the product information with the image by the server.

In one embodiment, storing the annotation content in the auxiliary information of the image and storing the image by the server may include:

storing in the auxiliary information of the image the product information that is linked by the URL in the annotation content and storing the image by the server.

A second exemplary method of image search in accordance with the present disclosure is described below. Descriptions about parts of the second exemplary embodiment that are equivalent or similar to those of the first exemplary embodiment can be found in respective descriptions in the first exemplary embodiment. The second embodiment focuses on the differences from the first exemplary embodiment.

FIG. 5 shows a flow chart of this exemplary embodiment. As shown in FIG. 5, the exemplary embodiment includes:

S501: A user client submits a request to a server through a network, requesting a web page to be opened.

S502: The server returns to the user client the requested web page that contains an image.

In one embodiment, the web page returned by the server contains an image and allows the user client to add annotation content for the image.

In another embodiment, a function of adding a frame label for the image is further provided in the web page returned by the server.

In yet another embodiment, the user client may add annotation content for the image through a text box provided in the web page.

At S503, besides adding annotation content for the image, the user client may further add a frame label.

At S503, besides adding annotation content for the image, the user client may further add a frame label to the image using a frame labeling function provided in the web page, and sends the frame label to the server. The frame label can be sent along with the annotation content to the server, for example.

If the user client performs frame labeling and adds annotation content for the image in the web page, then in one embodiment the annotation content may be added within an annotation box of the frame label.

With conventional web page technology, after a user client adds annotation content for an image in a web page or adds a frame label for the image (in addition to annotation content) in the browsed web page, an activity of submitting them to a server includes sending the image, the annotation content and the frame label (if included) to the server. It is noted that the image is included in the submission regardless of whether the image previously existed in the web page or has been uploaded from the user client in the current browsing event. On the other hand, current web page technologies utilized in the disclosed embodiments allow submitting only the annotation content for the image and the frame label (if included) to the server without resending the image when the image previously existed in the web page. This avoids transmitting the same content (i.e., the image in the web page in this case) back and forth between the server and the user client, thereby saving bandwidth and resulting in fast interaction for improvement of user browsing experience. The AJAX technology described above is one of these technologies.

S504: The server stores the annotation content for the image received from the user client.

Similar to the first exemplary embodiment, the following approaches may be used for storing the annotation content for the image by the server.

1. In one embodiment, the server stores the annotation content in a database and associates the annotation content with the image.

2. In another embodiment, the server stores the annotation content in auxiliary information of the image and then stores the image.

In case that the submitted content further includes a frame label for the image as described above, the server not only stores the annotation content for the image that is sent from the user client but also stores the frame label for the image. In particular, the server may further store the annotation content within the frame label through the above two methods.

The above two methods may store a URL link and have the information stored in a tabular form.

Specifically, the server needs to create an annotation parser in the latter method. In one embodiment, when an annotation is stored, the annotation parser writes the annotation content into the auxiliary information of the image. When the image requested for display is returned to the user client (e.g., after performing the activities of S505) and the search engine sends out a request for retrieving corresponding annotation content, the annotation parser parses out the annotation content from the auxiliary information of the image and returns the annotation content to the user client or, alternatively, returns the annotation content to the user client through the search engine.

S505: The server reckons the annotation content for the image as a search index which is provided to an image search engine.

In one embodiment, between S503 and S504, additional activities that may be included are described below.

S503′: The server examines the annotation content submitted by the user.

An examination at this point includes one or a combination of two of the following meanings: examination of the legitimacy of annotation content and examination for the best annotation content.

In one embodiment, when the server organizes a format of question and answer and a scoring rule for annotation content submission with users providing more annotation contents, the submitted annotation contents may be examined.

As with the first exemplary embodiment, when the server organizes a format of question and answer and a scoring rule for annotation content submission, the following may be used to implement storing the annotation content in a database and associating the annotation content with the image by the server:

storing in the database the best annotation content detected upon scoring and associating the best annotation content with the image by the server.

In one embodiment, the following may be used to implement storing the annotation content into auxiliary information of the image and storing the image by the server:

storing in the auxiliary information of the image the best annotation content detected after scoring and storing the image by the server.

As with the first exemplary embodiment, when the annotation content includes a URL address of the seller of the merchandise, storing the annotation content in the database and associating the annotation content with the image by the server may include:

storing in the database the product information in the web page that is linked by the URL in the annotation content and associating the product information with the image by the server.

In one embodiment, storing the annotation content in the auxiliary information of the image and storing the image by the server may include:

storing in the auxiliary information of the image the product information that is linked by the URL in the annotation content and storing the image by the server.

It is noted that the second exemplary embodiment refers to a specific situation when technologies such as AJAX are used on the one hand, and focuses on a situation when a user provides an answer to a question about an image on the other hand. Particularly for the latter situation, it is evident that the server may have already stored the image because the image may have been previously received by the server (e.g., the image has been uploaded by some user previously) or may be an image on the server. In reality, upon adding annotation content or frame label for the image by the user client, the server only needs to obtain the annotation content for the image and the frame label without repeatedly receiving and storing the image. If the AJAX technology is used in the web page, the user may only send the annotation content and the frame label to the server without repeatedly sending the image to the server.

The second exemplary embodiment is described from the perspective of the server below. FIG. 6 shows a flow chart of such description.

S601: The server receives a request and returns a web page. The returned web page contains an image and allows an addition of annotation content for the image.

In the returned web page, at S601, a client user is permitted to add a frame label for a portion of the image in one embodiment. As such, a user client may add a frame label for an image on a browser using this technology. Specifically, through this technology, the user client is provided with a function of frame labeling for a certain part of the image.

S602: The server receives and stores the annotation content for the image.

A textual input for annotation content may be a description written by the user client related to a merchandise in the image in particular, such as, for example, texture, material, place of production, unit price, function and use of the merchandise, a URL address of an online store of a seller of the merchandise, contact method of the seller and comments for the merchandise, or any combination thereof.

The content of the frame is typically a product (in the image) that is framed by the user client. Within the annotation content of the frame label there may be a description of the product and a URL address of the online store of the seller, for example, as described above.

In one embodiment, if the user client performs frame labeling for the image in the web page and adds annotation content, the annotation content may be added within an annotation box of the frame label.

It should be noted that what the server receives may be an annotation content and a frame label for the image added by a certain user, different annotation contents for the same image submitted by different users, or from the same user in multiple times, for example. Evidently, the latter may further include separately submitting multiple annotation contents and frame labels for the same image in multiple times.

Two implementation methods for storing annotation content for an image by the server are described below.

1. In one embodiment, the server stores the annotation content in a database and associates the annotation content with the image.

2. In another embodiment, the server stores the annotation content in auxiliary information of the image and stores the image.

For example, when the image is in jpg or jpeg format, the server may store the annotation content as user comments in accordance with the Exif specification.

S603: The server reckons the annotation content for the image as a search index and provides the annotation content to an image search engine.

In one embodiment, between S602 and S603, additional activities may include:

S602′: The server examines the annotation content submitted by the user.

In one embodiment, the server may organize a format of question and answer and a scoring rule for annotation content submission to facilitate more and better annotation contents provided by user clients.

When the server organizes a format of question and answer and a scoring rule for annotation content submission, the following may be used to implement storing the annotation content in a database and associating the annotation content with the image by the server:

storing in the database the best annotation content detected upon scoring and associating the best annotation content with the image by the server.

In one embodiment, the following may be used to implement storing the annotation content in auxiliary information of the image and storing the image by the server:

storing in the auxiliary information of the image the best annotation content detected after scoring and storing the image by the server.

In one embodiment, when the annotation content includes a URL address of the seller of the merchandise, storing the annotation content in the database and associating the annotation content with the image by the server may include:

storing in the database the product information in the web page that is linked by the URL in the annotation content and associating the product information with the image by the server.

In one embodiment, storing the annotation content in the auxiliary information of the image and storing the image by the server may include:

storing in the auxiliary information of the image the product information that is linked by the URL in the annotation content and storing the image by the server.

FIG. 7 shows a resulting view that implements the first and the second exemplary methods of the present disclosure. As shown in FIG. 7, upon searching through a search engine, a user can see a cover image of <<I am very busy>> of Jay Chou. The image already has frame labels and annotation contents. One frame label is a frame label of a shirt in the image on which a mouse cursor of the user is placed. The web page technology automatically provides a display of the annotation content. Within the annotation content there is information of that shirt, an icon linked to instant messaging with the seller and a price. Other frame labels can also be seen on the image. When the mouse cursor is placed on other frame labels, the web page technology will automatically provide displays of respective annotation contents. Furthermore, all questions about the image are listed at the bottom of the image. A user who browses this web page may add answers to these questions.

The image shown in FIG. 7 actually has many frame labels. FIG. 8 shows all annotation contents for merchandises in that image. Each of the annotation contents includes simple information of respective merchandise, a price and an icon that links to instant messaging with respective seller. Upon obtaining the image through a certain keyword search (e.g., a keyword of a certain merchandise), the user may obtain information of multiple merchandises in the image, thus extending likelihood of purchase by the buyer and facilitating more transactions to be concluded.
